Only part of frame image is visible when "Enlarge and show .... when a thumbnail is hovered over"

Small inconvenience when looking through alarm frames
/zm/index.php?view=frames&eid=17071744

frames are 720 x 480
image "when a thumbnail is hovered over" is to mach enlarged and it is for this reason cut off on the left to the size of column width.

first image on left side is cut off. When I add "Event id" column, thumbnail in horizontal view is longer.

on second attached file, after clicking on thumbnail the image is fully visible.

I get it. It's 5 times bigger then "Options / Web / WEB_LIST_THUMB_WIDTH" . I have decreased it and it's OK.
